The purpose of this report is to highlight lands acquired with 1997 and 2004 voter-approved bond funds, provide a historical record of Pima County’s land conservation efforts and consider how these properties contribute to Pima County’s long-term vision – the Sonoran Desert Conservation Plan. The report also provides a special feature on the evolution of conservation and land use planning in Pima County.
Reports on the development of a reconnaissance level numerical groundwater model of the Davidson Canyon and Cienega Creek watersheds. Includes recommendations for data that must be collected prior to completing environmental analyses for the proposed project.
The Augusta Resources Corporation proposes to construct the Rosemont Mine project in the northern Santa Rita Mountains. This report is a reconnaissance analysis of the conceptual flow and water balance in the area. The conceptual flow model for the area is based on topography, geology and precipitation and identifies the likely flow paths in the watershed and aquifer system. The water balance includes estimates of recharge to and groundwater flow from the area; there is no evapotranspiration discharge from the regional groundwater.
This report was drafted to facilitate discussion about protection of cultural resources under the Sonoran Desert Conservation Plan. The first part of the report provides an overview of historic preservation in Pima County, while the second part provides analysis and recommendations for improving Pima County's historic preservation policy.
Recommends where riparian land acquisitions would be most effective in serving as mitigation that would cover all priority vulnerable species identified in the SDCP. Priority is given to reaches of watercourses.
Provides background information on improved mapping techniques that have led to a proposal to update the Watercourse and Riparian Habitat Protection and Mitigation Requirements Ordinance adopted in 1994. New riparian classification maps will be forwarded to the Board to consider for adoption during 2003.
Invasions by non-native species cause serious problems in many parts of Pima County. It will benefit from adopting policies and increasing coordination with government and non-profit groups to deal effectively with invasive species.
A restoration effort of the San Pedro River to restore sacaton grassland, riparian trees and mesquite to about half the 50 acres of fallow agricultural fields at the Bingham Cienega. The overriding goals were to (1) establish a diversity of riparian habitats in the fields which in turn will support a greater number of invertebrate, reptile, mammal and bird species; and (2) develop practical techniques for promoting establishment of native plants that require little or no irrigation.
Describes a comprehensive regional policy direction to achieve meaningful riparian restoration necessary for endangered species compliance and the basic relation of water policy to conservation planning.
Provides a brief analysis of the legal and financial feasibility of the March 16, 2000 proposal, as well as a comparative analysis of (1) the conservation value, (2) the level of cultural resource protection, and (3) the fiscal impact of the proposal as measured against other development projects and against the various alternatives that might be exercised by the landowner.
